Q.
What is UBLO?
A. The UBLO
window system is designed with circular in window glass that can be opened and
closed with a lid for ventilation, inspired by the word "hublot,"
which refers to the round windows found on ships and airplanes.
Q. What is the reason for using UBLO window?
A.
It provides effective
ventilation without obstructing the view from the window. It ensures safe
ventilation without the hazard of falling or intrusion, maintaining a constant
flow of fresh indoor air to create a comfortable environment.

Q. Does the opening faciliate ventilation well given its small size? How many circular windows need to be installed for proper ventilation?
A. Installing two or more circular windows vertically can induce buoyancy-driven ventilation, ensuring effective airflow. The recommended minimum number of circular windows for installation is two, and it's advised to have at least one* circular window per 20m³ of room volume. Keep in mind that ventilation capacity decreases by 50% when using the filter.
* The number of windows required to achieve 0.5 ACH (Air Changes Per Hour) on one side of a room that is facing the exterior. This value has been calculated through simulations, and actual ventilation may vary depending on seasons and weather conditions. In rooms where two or more sides are oriented towards the outside, it becomes feasible to achieve cross-ventilation. As a result, the number of windows that are typically recommended for ventilation can be decreased. For more detailed information, please refer to the ventilation section in the technical brochure.
Q. Does UBLO window provide effective
airtightness and watertightness?
A.
Yes. The circular windows are designed with a
dual-sealing structure and a gas-tight compression gasket, ensuring excellent
airtightness and watertightness. They have been rigorously tested and certified
by KS accredited testing facilities, achieving the highest domestic grade of
level 1 for airtightness and level 50 for watertightness.
Q.
Can existing glass be
used?
A.
Drilling holes in existing
glass poses a risk of breakage, and for optimal performance in terms of wind
pressure resistance, insulation, airtightness, and watertightness, new glass
needs to be manufactured.
Q.
Can UBLO windows be installed
on double or triple glazing?
A.
Yes, UBLO windows can be
installed on double or triple glazing, with a thickness of up to 48mm. For
double or triple glazing, UBLO provides customized glass with circular
apertures and ventilation window sets with appropriate glass thickness,
specifications, and insulation gaskets for the specific site.
Q.
Can I have the glass made by a
third party company?
A.
To ensure the quality, UBLO
handles the manufacturing and delivery of the glass directly. For single-pane
glass, you can opt to have it produced by another glass company to match the
aperture size, provided it's tempered glass. However, if you choose a different
supplier for glass and installation, UBLO won't be able to guarantee the
glass's performance and potential defects.
Q.
Is it possible to buy just the
circular window set without the glass?
A.
For single-pane glass, you
have the option to purchase the circular frame alone. However, when it comes to
insulated glass, such as double or triple glazing, UBLO offers a comprehensive
package including glass with the aperture and a UBLO window set, complete with
glass thickness and specifications customized to your specific site
requirements.
Q.
What are the specifications for the circular
window? Can the size be customized?
A. The standard
dimension for the circular window's opening is a diameter of 148mm (glass
aperture diameter of 180mm), and it is sold in this single size specification.
+ Ublo SpecificationsQ.
Who handles the installation?
A.
For the installation of
insulated glass, clients can choose between the window installation service
recommended by UBLO or an external window installation contractor. In the case
of single-pane glass, customers can directly perform the installation of the
circular window and a installation manual will be provided along with the
delivery.
Q.
Can UBLO window be installed
on non-glass walls?
A.
The circular windows can also
be installed on materials such as polycarbonate panels like Danpalon, as well
as wood or metal panels with thicknesses ranging from 8 to 48mm. For concrete
walls, due to thicker connection points and potential challenges in ensuring
airtightness and watertightness, it's recommended to contact UBLO for detailed
inquiries and recommendations.
